Abstract

Tempe bacem is a kind of tempe product that has spicy and sweet taste. The shelf life of this product is very short. The objective of this research was to increase tempe bacem’s shelf life by vacuum and non-vacuum packaging that stored in different conditions. Tempe that used in this research was in round form with 5 cm of diameters and 1 cm of thick. Tempe bacem was processed by selected formula, packaged by vacuum and non-vacuum and then stored in room condition (26-300C) and refrigerator condition (100C). Total protein in this product was 33.7% (db), fat 0.9% (db), ash 3.0% (db), carbohydrate 66% (db), while antioxidant capacity was 194.65 mgAEAC/100 g tempe. The pH value in tempe bacem was 5.7, lightness 35.9, hardness 2848.5 gram force, total TPC 1.8x103 CFU/g and total koliform <3.0 MPN/g. The shelf life of tempe bacem that packaged by non-vacuum method in room condition was 2 days, and in refrigerator condition was 6 days. The shelf life of tempe bacem that packaged by vacuum method in room condition was 3 days and in refrigerator condition was 18 days.
